Abstract

The invention provides a rice brown planthopper pest monitoring method and device. The monitoring method comprises the steps that one or more of linalool, monoterpene-beta-ocimene and 2-heptanol which are released by rice and are used for seducing brown planthoppers are monitored through chemical sensors, and when it is detected that one or more of the linalool, the monoterpene-beta-ocimene and the 2-heptanol exceed a preset threshold, an alarm is given. The chemical sensors are a linalool sensor, a monoterpene-beta-ocimene sensor and a 2-heptanol sensor. By the usage of the rice brown planthopper pest monitoring method and device, a volatile organic compound which is released by the rice in different growth periods and used for seducing brown planthopper pests can be automatically and continuously monitored in real time, and an early warning is issued in time. Compared with methods such as an image processing technology, an early-warning model and bibliometrics which are adopted by current paddy field pest early-warning, the rice brown planthopper pest monitoring method and device have superior timeliness.

Description

technical field [0001] The invention relates to modern planting technology, in particular to disease and insect pest monitoring technology in modern planting. Background technique [0002] Rice is the main food crop in my country, and brown planthopper is an important pest in rice production. Brown rice planthopper is a kind of rice planthopper. The brown planthopper has the habit of long-distance migration, and is currently the primary pest of rice in my country and many Asian countries. The brown planthopper is a monophagous pest and can only feed and reproduce offspring on rice and common wild rice. [0003] During the growth and development of plants, they will release volatile organic compounds (Volatile Organic Compounds, VOCs), including alcohols, aldehydes, ketones, esters, mushrooms and aromatics, etc. These volatiles transmit plant identity and its Physiological status and other information play the role of chemical communication substances in the relationship be...
